Remains of the Jewish second temple may have been found during work to lay pipes at the Al-Aqsa mosque compound in east Jerusalem, Israeli television reported Thursday. Israeli television broadcast footage of a mechanical digger at the site which Israeli archaeologists visited on Thursday. Gaby Barkai, an archaeologist from Bar Ilan University, urged the Israeli government to stop the pipework after the discovery of what he said is “a massive seven metre-long wall.”

Television said the pipework carried out by the office of Muslim religious affairs, or Waqf, is about 1.5 metres deep and about 100 metres long.

The compound, which houses both Al-Aqsa Mosque and the Dome of the Rock, is located in east Jerusalem, which Israel occupied in 1967 and then annexed. It is the third holiest site in Islam after Mecca and Medina.
